Application filed November 16, 1916.

To aZZ whom it may concern:

Be it known that l, (Juana-us W license, a citizen of the United States,residing at Liberal, in the county of Seward and a State of Kansas, haveinvented certain new and useful Improvements in l lydrocarbon- Burners,of which the following is a specification.

This invention relates to an improvement in in hydrocarbon burners andmore particularly to burners of the type intended for use in connectionwith crude oil or heavy distillates, although it will be understood thatthe same structure might be employed in light distillates. An object ormy invention is to provide a urner having a vaporizing cup or plate soformed that the sizeof the flame can be controlled by regulation of theoil supph no and thus the heat given out by the burner can be accurate.y regulated through several predetermined degrees.

A further object lies in so constructing the vaporizing cup or platethat in its genof a conical-form- With a cup at the apex, andsubstantially circular or ring shaped cups formed around this cup atvarious heights-or levels on the sloping side of the conical form of thevatill perusing plate, thus providing, a vaporiz ing cup structure Whichpresents the com I tral cup and the ring shaped .cup in such relationthat the volatile oil is fed to the'cup and if a suflicient volume isnot supplied to an flow over the rim. edge of this cup, vaporizationwill take cup and as the the gas rises place only from the one surfacearea from which is hunted only a small amount of'gas Will be generated,Whereas it" the vol: atile, oil is supplied in suficlent yoluine toilovvover the rim edge or the central cup into the ring shaped cup the"superficial area oi. liquid 1s not only increased,

over the rims of the various cups vvill be ily vaporized and thus thegas geueration Will be considerablyaugmented. This formation of the"vaporizing cone in the \fnonioal form further so liberates the gas Iupon volatiliaation of the oil that the burning gas is spread morethroughout the area (of the fire pot of the stove or furnace inSpecification of Letters Itateut.

tel-mingling of the :tresh gas as generated.

Yet another object lies in so constructing the vaporizing cone that itcan be placed in use with other burner parts especially constructedtherefor or can be fitted to rious types of burner structures as nowalready installed and in use.

With the above and other objects in view, my invention consists ofcertain novel few tures of construction and combinations of parts whichwill be hereinafter set forth in connection With the drawings and thenmore particularly pointed out in the claim.

lln the drawings Figure l-is a view in vertical section showing one formwhich the burner might take.

Fig. 2 is a transverse sectional view taken on the line n+2 of Fig, l,

The burner structure is intended to be installed in the fire box oi astove, furnace, or the like, and it will consequently be underairsupplywith the jstoo'd that changes and variations in the form and arrangementof the partsivill necessarily be made for different adaptations. In thepresent disclosure I have illustrated the device in the form which itmight take When built into a heating or cooking stove of the usual Woodor coal burning type, and here a base plate 1 is shaped to have the rimedge and has the central portion thereof raised indicated at 3. Ah airsupply duct 4- is located at one side of the base plate 1 and is curvedat its upper to overhang the raised central portion 3 of the base plateand to have an air discharge mouth opening 6 discharging air downtrallydisposed over the baseplate l, a valve being connected in this supplypipe 7 to control andregulate the flow of oil therethrough. Ininstalling the structure as described, the base plate Will be fitted inthe fire pot of the usual form of stove or a special stove might beprovided and in either end as shown at i .Whichthe burner is being usedand a better v case this base plate is inounted'to have an Ml combustionoccurs through more ready 1nair tight connection around its edge, theair passages; however being left open. The supply pipe 7 will beextended to a suitable source of oil supply and the valve 9 will belocated at any convenient point, it of course being understood that itis preferable that some means be arranged to control the passage of airthrough the duct or passage. l. All of the parts as described are ofsubstantially standardv form and might be varied practically withoutlimitation to bring the device to fit the particular use to which it isto be put, this part of the structure being flexible even to the extentthat the raised portion 3 of the base plate might be dispensed with andthe air supply passage might be arranged to be entirely independent ofthe base plate, although it is perhaps desirable that the air passage bedisposed somewhat after the manner shown as the heating of the air inits passage to the burner not only causes better circulation but alsocauses the hydro-carbon oilto be more readily vo'latilized.

A vaporizing cone which is generallv indicated by the numeral 10 is madeto be substantially conical in its general outline, and at its apex thismember 10 has an oil recess 11. The member 10 is shaped on its bottomportion to fit substantially over the top of the raised portion 3 and itis perhaps desirable that these parts be mate'd so that the vaporizingcone will be held at all times in a predetermined relation where therecess 11 is immediately beneath the discharge end 8 of the-oil supplypipe 7 and is consequently centralized beneath the air discharge opening6 of the passage 4. The oil grooves 12, 13, and 14, which in the presentdisclosure are made of substantially ring shape and are'disposedconcentrically around the recess 11 are formed in stepped relatipn sothat each takes a lower level than the recess next in size, and thus asoil is sum'ilied into the recess or cup 11, in a sulTicient quantity toflow over the top rim edge thereof, this oil will flow down over thesubstantially perpendicular inside wall of the next adjacent ring likerecess or cup and the How will be from the one ring like recess or cupto the other, of course depending upon the rate of flow of the oil andthe volatility thereof. Where only a small. quantityof oil is suppliedthrough the pipe 7,

the volatilization of this oil will be at such a rate that there willnot be any flow over the rim of the recess 11 into the next adjacentrecess or cup-12 and, consequently the surface from which thevolatilization of the oil occurs will be comparatively small in itsarea. This relatively small area of oil will give oil a correspondinglysmall vol-' ume of combustible gas andthus the flame supplied by thisvolume of gas will be of small size however immediately the supply ofoil is increased to such an extent that recess or cup 12 will increasethe area from which gas is rising due to the volatilization of the oilthrough the heated surrounding air, and consequently the flame volume isconsiderably increased and intensified. v This action will of course beunderstood to be increased as the flow of oil is increased to createoverflow from one cup to another and thus it will be seen that in theform of device as shown in the present illustration, by, manipulation ofthe valve 9 the supply of oil can be controlled to such an extent thatfour various degrees of burner flame and consequently four regulationsof heat can be made, and even then other variations are obtainableintermediate the main steps or divisions of rise or fall.-

While in-the illustrations I have shown only one form of the vaporizing"cone, namely the form in which the member 10 is made of substantiallyconical configuration with a central orifice or cup 11 and the ringshaped cups or recesses 12, 13, and M arranged concentricallytherearound, it will be appreciated that in some adaptations the member10 might partake of the form of'a pyramid, might present a rectangularor elliptical base outline with the side walls raised in the gradualincline or slope to a common center or to a ridge center, and that insome adaptations the pitch or angle of the side might also be variedwithout limitation, the structure being such that under somecircumstances itmight even be found practical to make the rim edges ofthe several cups or recesses to lie in substantially the same plane. Itwill further be apparent that other changes might be resorted to in theform and arrangement of this member 10 to fit the same for various typesof burn- 'ers, however, as all of these forms will be used only to itthe device for various adaptations and as all are outgrowths of. thestructure illustrated in the drawings, it is not deemed necessary tohere endeavor to make showing of all of the modifications which might beresorted to and it will be understood that the above are only some ofthe forms which might be taken by the vaporizing cone l0.

From the foregoing it will be seen that I have provided a vaporizingcone and a burnerembodying the same in such a man-- ner that crude oilor other heavy distillate, or light oil and light distillates can beburned with maximum efliciency, that the "Ill Ski

aaaaeie the other from the outer edge toward the in such relation centerdisposes the same that the air as supplied for the purpose ofvolatilizing the oil and supporting combustion Will spread the flame togive the greatest heating action, and that the supply of air and thepassage of the same adjacent to the vaporizing plate in the manner asset forth will give better vaporization and a better combustible mixturethus practically eliminating the formation of carbon or the giving oilof smoke or gases during burning. While only one specific form of burnerand one particular design and type of vaporizing cone have beenparticularly illustrated, it will be evident that changes as set forthabove and othervariations can be resorted to in the form and arrangementof the parts, and hence I do not Wish to limited to the exact disclosurebut only td such points as may beset forth in the claim.

:An oil burner comprising a base plate his having a rim edge, said baseplate having its central portion raised to provide an annular groovetherein, for receiving oil a vaporizing cone having a plurality oiconcentrically arranged ring; shaped oil re ceiving cups formed in theslopin sidewall around the central oil retaining" cup and pro vided withsubstantially perpendicular inside walls, said vaporizing cone being supported by said raised central portion, so that the cone will be abovethe level of the oil in the annular groove of the base-plate and an airsupply passage dctachably connected to one side of the plate, the upperend of said passage being" curved to oven hang the central oil retainingcup oil the vaporizing; cone.
